CORRELATIONS
Art: Clay-modelling and drawing exercises on the whole plant, and also upon the ear.
Literature: Interpretation and reading of "Blessing the Corn-fields", from Hiawatha.
History: The name Indian corn originated in the early colonial days of the Eastern and Central States, when the pioneers obtained corn from the Indians. The Indians showed the settlers how to kill the trees by girdling and how to plant the corn among the standing trunks, and thus have corn ready for roasting by August, and for grinding into meal or for boiling to make hominy by September.
